Factors That Lead to the Extinctions of Wildlife

Wildlife is the term used to describe all of the different animals, birds, fish, fungi, and other organisms that exist in the natural environment without human influence. This includes deserts, forests, rainforests, grasslands and other ecosystems throughout the world.

Increasing demand for wildlife and the resulting exploitation of their resources, such as timber, leather goods, seafood, medicinal ingredients and textiles, have been major contributing factors to the decline of many of these species. Some of the most vulnerable ones, like tigers and elephants, are particularly impacted by the trade in illegal products from their habitats, which is a key concern for WWF and its conservation work.


The loss of forests is another major cause for the extinction of many species. The growing demand for land and building materials requires the cutting down of trees and the destruction of their habitat. Often, the forest-dwelling creatures have to relocate in search of new habitats. This is a difficult task as they have to face many obstacles while searching for a place to live.

Environmental pollution is also a major threat to wildlife as it affects their habitat, and the food they consume. The pollution from various industrial processes and air and water pollution can severely impact the lives of wild animals, as well as humans living nearby.

Urbanization and population explosion are two other major causes for the extinction of wildlife. The development and growth of cities mainly leads to the development of sewage systems that pollute water bodies and the surrounding area, which is detrimental for many animal species. The influx of people, whose lifestyles primarily depend on consumption of foodstuffs that are not found in the wild, has resulted in a rapid decline in wildlife populations.

Hunting for subsistence and recreation is another factor that has contributed to the decline of wildlife. The practice of hunting is an important part of the culture of many communities, including tribes in southern Africa and northern Asia, and it is still widely practised today.

Poaching is also a big threat to wildlife. It is a form of animal trafficking that occurs on both the domestic and international levels, and is an increasing problem for many endangered species.

In addition, over fishing is a major problem for some marine animals. It destroys their habitats and limits their food supplies, which leads to the loss of the animals that they feed on.

The use of pesticides is also a significant issue for many species, and it can be damaging to their health. In some cases, it can even harm the young and weak of these animals.

Increasing global temperatures are another significant concern for wildlife, as they threaten the balance of our planet’s ecosystems and can cause the death of many species. It is essential to take steps to curb the effect of global warming on wildlife and their habitats, as a healthier environment can help to reduce illness and improve the quality of life for all.
